Crystals Procurement Notes

Verify the specific load capacitance and temperature range requirements against the system design specifications before procurement. Confirm that the 9 pF load capacitance aligns with the oscillator circuit's total stray capacitance. Ensure the operating temperature range of -40°C to +85°C meets the environmental conditions of the intended application. Check for RoHS compliance documentation if required by regulatory standards.

Crystals Selection Notes

Select this component when a compact 50 MHz reference signal is required for space-constrained digital circuits. The 4-SMD package facilitates automated surface-mount assembly processes. Consider the 50 Ohm ESR limit when designing the oscillator circuit to ensure reliable startup. The wide temperature range makes it suitable for consumer electronics and industrial IT applications where thermal variations are expected.

Crystals Part Context

This part belongs to the TXC 7M series of SMD seam-sealing crystals. These units are characterized by their miniature footprint and robust sealing technology, which protects the quartz element from moisture and contaminants. The series is designed to replace larger through-hole crystals in modern portable and high-density electronic designs.

Crystals Replacement Considerations

Direct substitutes must match the 50 MHz frequency, 9 pF load capacitance, and 4-SMD 3.2x2.5mm package dimensions. Verify that alternative components meet the same ±7 ppm tolerance and -40°C to +85°C operating temperature range. Ensure the replacement maintains the 50 Ohm ESR specification for circuit compatibility.
